php 计算小时数并化整为零

复制代码 代码如下:


/* Author: 杨宇 yangyu@sina.cn */
//参数$hours_min为数组,数组的格式为1:10,返回为1小时
/*
例如:
$hours_min[0] = '1:10';
$hours_min[1] = '2:30';
echo hours_sum($hours_min);

输入为4,也就是合计4小时

*/
function hours_sum($hours_min){

if (!is_array($hours_min)) return false;

$tmp_arr = array();
foreach ($hours_min as $v){
$tmp_arr = explode(':',$v);
$hour[] = $tmp_arr[0];
$min[] = $tmp_arr[1];
}

$hours = array_sum($hour);
$mins = array_sum($min);

$mins = $mins >= 10 ? str_pad($mins, 2, 0, STR_PAD_RIGHT) : $mins;
$hours += floor($mins/60);
$hours += $mins%60 >= 30 ? 1 : 0;
return $hours;
}


将日期转化为星期

复制代码 代码如下:


/* Author: 杨宇 */
//输入的$data参数为,yy/mm/dd 或者 yy-mm-dd,返回星期几
function getWeekDay($date) {
$date = str_replace('/','-',$date);
$dateArr = explode("-", $date);
return date("N", mktime(0,0,0,$dateArr[1],$dateArr[2],$dateArr[0]));
}


PHP将秒转化成小时和分(格式为 ** 小时 ** 分)

复制代码 代码如下:


/* Author: 杨宇 */
//将秒(非时间戳)转化成 ** 小时 ** 分
function sec2time($sec){

$sec = round($sec/60);
if ($sec >= 60){
$hour = floor($sec/60);
$min = $sec%60;
$res = $hour.' 小时 ';
$min != 0 && $res .= $min.' 分';
}else{
$res = $sec.' 分钟';
}
return $res;
}
